48 DENDROBIUM. 



D. Griffithianum. 



Eudexdrobium — Calostachyce. Sterns 12 — 18 inches high, obscurely 

 four-angled, furrowed, attenuated below into a long, slender foot-stalk, 

 and bearing near their summit 3 — 5 oval-oblong, extremely leathery, 

 deep green leaves, the broadest of which are 2 inches wide. Racemes 

 pendulous, 8 — 10 inches long, many-flowered. Flowers nearly 2 inches 

 across, bright yellow, the lip orange-yellow ; sepals oval-oblong ; petals 

 broader, sub-orbicular ; lip orbicular, with a convolute claw, margin 

 fringed, very papillose above.

 n. s. t. 258. De Puydt, Les Orch. t. 16. 



A rare species discovered by Griffith in British Burmah in 1833 — 4 



(locality not given), but not introduced till upwards of forty years 



afterwards. Its nearest affinities are the equally rare Dendrobium 



Paljpebrce and the well-known D. densiflorum ; from the former it 



differs in the colour of its flowers and in the structure of the lip; 



from the latter by its usually shorter stems, with deeper green, 



more leathery leaves, and by its more lax racemes of flowers, that 



are larger, and have broader segments. It flowers in May and 



June. The variety, which is also extremely rare, appeared in the 



collection of M. Guibert, an amateur of Paris, about the year 1876. 



M. Guibert's plaut was probably the only one ever imported. 



D. Harveyanmn. 



Eudendrobium — Calostachyce. Stems fusiform, 6 — 9 inches long, but 

 sometimes much shorter. Leaves in twos and threes at the summit 

 of the stems, ovate-oblong. Peduncles from the uppermost joints, 3 — 4 

 or more flowered. Flowers about 2 inches in diameter, bright canary- 

 yellow ; sepals lanceolate, acute ; petals elliptic-oblong, furnished with 

 a flexuose, branched fimbriation, similar to that of the lip of Dendro- 

 bium Brymerianum but less pronounced; lip orbicular, concave, with 

 fringed margin and papillose upper surface ; spur short, refuse. 

 Dendrobium Harveyanum, Rchb. in Gard. Chron. XIX. (1883), p. 624. 

 Introduced in 1883 from British Burmah, by the Liverpool 

 Horticultural Company. It is dedicated to Mr. E. Harvey, of 

 Aigburth, near Liverpool, in whose collection it flowered for the 

 first time in this country, in May of the same year. Its most 

 striking characteristic is seen in its curiously fimbriated petals.
